How do i get nutrients if i can't eat solid foods?

Liquids: If you for some reason can't take any solids then you can get your nutrients via liquid supplements such as milk shakes (boost for example), protein shakes. I would also take a daily multivitamin if you are able to take pills either whole or crushed. Of course of this is long term then you certainly need to explore more long term options. For a short time however these things could work.
